[PATCH] virtio-pci: alloc only resources actually used.
Move resource allocation from common code to legacy and modern code.
Only request resources actually used, i.e. bar0 in legacy mode and
the regions specified by capabilities in modern mode.

[PATCH RFC 0/5] virtio_pci: modern driver
Based on Rusty's patches.
Coding style and funny jokes are his.
Bugs and a star wars reference (should be easy to spot) are mine.
Untested, but useful as basis for beginning the qemu work.
TODO:
= simplify probing: use a common probe function, probe with modern driver
first, if that fails - probe with legacy driver.
BUGS: ATM legacy driver can win and drive a transitional device

[PATCH v2 0/2] vfio: blacklist legacy virtio devices
Legacy virtio devices always bypassed an IOMMU, so using them with vfio was
never safe. This adds a quirk detecting these and disabling VFIO unless the
noiommu mode is used. At the moment, this only applies to virtio-pci devices.
The patch might make sense on stable as well.
